So you’ve noticed that your Hydrangea isn’t growing properly but don’t worry, they can be a little tricky. Depending on the type of hydrangea that you’re growing in your garden there may be certain care tips to follow.
Color
All hydrangeas undergo some color change as they age, but only bigleaf and mountain hydrangeas can change their color in a predictable, controllable way. It is not solely the pH of the soil that is responsible for this change but it is actually the presence of aluminum in the soil.
Wasson Nursery carries Aluminum Sulfate in our garden centers if you’re interested in deepening the blue of your hydrangea. It is easier to change the color from pink to blue than it is from blue to pink, but both processes involve making chemical application in specific amounts at specific times. A soil test is also necessary to determine the best course of action.
Note: Pennies, nails, aluminum foil or coffee grounds in the soil will not change the color!
Growing Tips for Success!
- Plant your Hydrangea moist but well-drained soil.
- Some sun each day is ideal. Most people think of hydrangeas as shade plants but they will look and flower best if they have at least 4 hours of sun (ideally in the morning).
- Give them plenty of water, especially as they are getting established. Hydrangeas have shallow roots so they dry out rather quickly.
